试验设计、设定与病人多中心随机对照试验，2331名医学上稳定的门诊心衰患者，左心室射血分数小于等于35%。
Design, Setting, and patients Multicenter, randomized controlled trial among 2331 medically stable outpatients with heart failure with left ventricular ejection fraction of 35% or less.
这一发现与患者的左心室射血分数——衡量左心室功能的一项参数——无关。
This finding applied to patients irrespective of their left ventricular ejection fraction, a common measure of ventricular function.
目的评价实时三维超声心动图(RT 3de)测量左心室容量与射血分数的准确性。
Objective To assess the accuracy of real-time three-dimensional echocardiography (RT-3DE) for measuring left ventricular volume and ejection fraction.
静息状态下，左心室舒张功能指标-二尖瓣室间隔角(msa)与射血分数(EF)呈负相关。
Mitral septal Angle (MSA), an index of left ventricular diastolic function, was negative correlative relationship with ejection fraction (ef) in the rest.
对照组与治疗组同期对应比较，左心室形态逐渐扩大，6个月末最明显，且差异有显著性意义。 同时左心室射血分数同组和两组间对应比较，均有明显改善（P<0.05，P<0.01）。
Results The changes of left ventricular shape and geometry in control group were more obvious than those in treatment group from early phase to 6 months(P<0.05, P<0.01).
术后患者左心室舒张末径有明显缩小；术后2 9 0个月左心室射血分数与术前相比，有显著提高。
The left ventricular end-diastolic diameter and left ventricular ejection fraction were improved significantly 29.0 months after operation.
术后患者左心室舒张末径有明显缩小；术后2 9 0个月左心室射血分数与术前相比，有显著提高。
The left ventricular end-diastolic diameter and left ventricular ejection fraction were improved significantly 29.0 months after operation.
